To a/ZZ whom it may concern: V

Beit known that I, CHAPIN WAGNER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Plow, of which the following is a specification.

My inventionwis an improved plow; andn it consists in the peculiar construction and combination of devices hereinafter fully setffor'th and claimed.

In the accompanying drawings, Figure 1 is a side elevation showing the mold side'of the standard and landside, the posit-ions of theVV 'point and moldboard being indicated in dotted lines. Fig. 2 is aside elevation from the landside of my improved plow.' Fig. 3 is a detail :sectional view taken through the landside standard and point on a'plane indicated by the line a `a of Fig. 1. Fig. 4 is a vertical sectional view taken through the landside and standard on a plane indicated by the line b b in Figs. 1 and 2. Fig. 5V is a sectional View through a portion of the standard and point on a plane indicated by the line c c of Fig. 1.'

The standard 1 is of cast metal and is provided with a gained bearing-face' 2 on one side for the front portion of the landside and isV provided with a bearing-face 3 for the point 4 and nioldboard 5. The landside is indicated by the reference-numeral 6. Above the gained landside-face 2 of the standard is formed an overhanging bearing-flange 7, which bears on the upper edge of the 'landside and is dovetailed, as at 8, the upper edge of the landside 'provided with a flan ge 15, which-bears against being correspondingly formed, so that a dovetailed joint is formed between the upper edge of the landside and the overhan ging flange of the standard to wedge the landside closely against the gained bearing-face ofthe standard to prevent the landside from working loose from the standard and prevent earth from working between the landside and the `stanpd ard. It will be-understood that by thusrforlning the standard with the overhanging bear-l ing-flange 7 and forming a dovetailedjoint between said standard and the upper edge of the landside the latter is effectually prevented from working upwardly on the standard and getting out of suck. At the front end of the landside the same is provided on the mold side thereof with an overhanging flange 9, in the rear side of which is formed an angular side.

groove 10, the sides of which converge forwardly.` At the lower front corner of the The standardis provided in its front side Alandsideis a vertical bearingsl1ou1der11.` i 55 or edgewith a gain 12, adapted to receive the laterally projecting or overh'anging flange 9 of the landside', andthe 'said gained portion 12 of the standard is formedwith a tongue 13 at the front edge of the standard, which tongue enters '-the groove l0 in the rear sideof the landside-Han ge 9,which Iiange when the landside is secured to the standard is fiush with the mold-face-3 of the latter.

Itrwill bev understood from. the foregoing description that owing. to the gain 12 inthe front edge of the standard and -the iiange 9 of the landside, against which the fronte'dge of the standard abuts, the draft is applied directly 4from the standard to the said landside, and thebolt 14, which passes through the ,latter near its lower` edge and through the corresponding portion of the standard, as shown in Fig. 4, is entirely relievedy of -stress yoccasioned by the draft. It will be further lunderstood that owing to-the tongue 13'on the front edge of the standard'and the groove 10 in the rear side of Vthe landside-ange 9 the stress on the landside `occasioned by the draft of the plow will tend to fit the front end of the landside all the more firmly to the front edge ofthe standard and effectually prevent vthe possibility of the landside Working loose p .from the standard.

The point 4, which also forms the colter, is

front edge of the standard and contributes tof keep the landside firmly locked to the standard. The abutting shoulders l1 16 of the landside and point, respectively, and the flange 15 n of the point, which bears against the front edges of the'landside and standard,effeetually prevent the point from slipping rearwardly under the stress of the draft, and thereby the bolt 17, which is also used to connect the point to the standard, is entirely relieved of all stress which might otherwise be occasioned loo by the draft. The landside has its mold-face 3 formed at its lower rear corner with a projecting tongue 18. The point is formed with a corresponding lng 19, which bears under and on the inner side of the said tongue, and hence the standard and point are interlocke-d by the said tongue and lug, and the point is locked firmly to its seat on the standard.

The moldboard 5 is secured to the standard by the usual bolts. The moldboard is of the usual construction and forms no part of my present improvements.

Having thus described my invention, I claiml. In a plow, the combination of a standard having a gain in its front edge, with a landside having at its front end a laterally-extending flange bearing on the said gained front edge of the standard, substantially as described.

2. In aplow, the combination ofl a standard having a gain and a tongue in its front edge, with a landside having at its front end alaterally-extending ange bearing on the said gained front edge of the standard, said flange having a groove formed therein, to receive the said tongue of said standard and thereby interlock the front edge of the standard and the front end of the landside, substantially as described.

3. In a plow, the combination of a standard having a gain and a tongue in its front edge, with a landside having at its front end a laterally-extending iiange bearing on the said gained front edge of' the standard, said fiange having a groove formed therein, to receive the said tongue of said standard and thereby interlock the front edge of the standard and the front end of the landside, said groove and tongue being correspondingly beveled to form a dovetailed joint between said flange and said gained edge of the standard, substantially as described.

4. In a plow, the combination of a standard having a gain in its landside-face, and an overhanging flange over said gain, said iiange having a descending bevel, with a landside fitting in said gain and having its upper edge beveled to correspond with said beveled fiange of said standard to form a dovetail or wedge 1 joint between said standard-flange and said landside, substantially as described.

5. In a plow, the combination of a standard having a gain in its front edge, a gain in its landside-face, and an overhanging flange over said last-mentioned gain, with a landside in said landsidegain and bearing under said flange, said landside having a laterally-extending flange at its front end, fitting in and engaging said gain in the front edge of said standard, whereby the landside and standard are interlocked to prevent the landside from moving upwardly or rearwardly on the standard, substantially as described.

G. In a plow, the combination of a standard having a gain in its front edge, a gain in its landside-face, and an overhan ging flange over said last-mentioned gain, with a landside in said landside-gain and bearing under said ange, said landside having a laterally-extending fiange at its front end, itting in and engaging said gain in the front edge of said standard, whereby the landside and standard are interlocked to prevent the landside from moving upwardly or rearwardly on the standard, and a point overlapping the joint between said standard and said landside-flange, said point having a flange bearing on the front edges of said standard and said landside, substantially as described.

'7. In a plow, the combination of a standard having a gain in its front edge, a gain in its landside-face, and an over-hanging flange over said last-mentioned gain, with a landside in said landside-gain and bearing under said flange, said landside having a laterally-eX- tending iange at its front end, fitting in and engaging said gain inthe front edge of said standard, whereby the landside and standard are interlocked to prevent the landside from moving upwardly or rearwardly on the standard, and a point overlapping the joint between said standard and said landsideange, said point having a fiange bearing on the front edges of said standard and said landside, said point and said landside having angular abutting shoulders at the lower4 front corner of said landside, substantially as described.

S. In a plow, the combination of a standard having a projecting tongue, with a point secured on the standard and having a lug on its under side to engage the front and under sides of said tongue, and thereby form an ini terlocked connection between said point and standard, substantially as described.

In testimony that I claim the foregoing as my own I have hereto atfixed my signature in the presence of two witnesses.

CHAPIN WAGNER.
